A Game-theoretic Approach to Spectrum Sharing in Cognitive Radio Networks
Shao Yu-bin · Journal of Nanjing University of Posts and Telecommunications · 2011
A game-theory based static spectrum sharing model is proposed for cognitive radio,which supports multiple secondary users competitively sharing one primary user system's idle spectrum.The primary user system's benefit function based on Self-discipline mechanism is established.Reasonable price is determined considering both primary user's spectrum demands and no wasting of the remaining free spectrum.Dynamic spectrum sharing algorithm is introduced,in which the secondary users can continuously adjust their strategies to reach Nash equilibrium and maximize their benefits.
